Diogo Cabral achieved his B.Sc. in Computer Science Engineering at FCT/UNL. During his B.Sc. studies, he participated in the Erasmus/Socrates Exchange Program, at the Facoltà S.M.F.N., Università di Pisa, Italy. In the last years of his graduation, Diogo Cabral became highly interested in multimedia and human-computer interaction fields. The work developed in his diploma project was the background for the mEmLearn project, awarded with the HP Technology Teaching Grant Initiative 2006. The mEmLearn project had the goal to promote the usage of Tablet PCs on education, developing new ways of annotation and interaction with this technology. Diogo Cabral worked 3 years as research assistant at CITI/FCT/UNL, which led him to pursue a M.Sc. in Computer Science Engineering degree at FCT/UNL. Currenly, Diogo Cabral is a Ph.D. Computer Science student at CITI/FCT/UNL, with a scholarship from the UTAustin|Portugal, Digital Media program. In his Ph.D. work, Diogo Cabral proposes the usage of pen-based technology for the manipulation of digital video, aiming to improve the digital media human interaction and combining multimedia and human-computer interaction research topics. In the context of the TKB project, Diogo collaborated in the development of Creation Tool, a multimodal video annotation tool for contemporary dance.
